hi can someone tell me which clutch will fit an escort 1.6 zetec fitted into a 1998 fiesta with ib5 gearbox , i have just fitted it all in and run it up to find the std escort clutch is not fully releasing and upon measuring it up i see the flywheel / clutch assembly is 20mm to thick so the release bearing is holding the clutch out , i am thinking focus possibly , any help appreciated
